The research design that allows researchers to answer causal questions about manipulated and measured variables is a(n) ______.
A) experiment
B) quasi-experiment
C) case study
D) correlational study

Question

Quizplus · Accepted Answer

An experiment involves the manipulation of one or more variables and the measurement of their effects on other variables. This design allows researchers to establish causality between variables by manipulating an independent variable and observing the effects on a dependent variable. Quasi-experiments, case studies, and correlational studies do not involve the manipulation of variables and are therefore not able to establish causality.
